WILLIAM A. BARBER, 0F WASHINGTON VERTICAL SICKLE DIVIDR FOR Applicationlled November when the grain stands up but when the grain is tangled anddown and full of vines, the arrangement provesl very inefficient. Theswathl of tangled grain, cutl by` the binder, hangs over the dividerboard and stays there vuntil the operator stops his machine and clearsthe board.- lf the grain is full of vines the efliciency becomes stillmore impaired. By the use of my improved structure, such conditions areentirely done away with because long before the grain` is cut by thebinder sickle, a clean-cut positive separation is made between thebinder swath and the uncut grain. By the use of the device desci-ibedherein clogging of the elevators and the binding mechanism of a binderis practically eliminated there being a continuous and uniform movementof the-grain as soon as out by the binder sickle to the elevators andbinding mechanism. This device causes a clean-cut, straight and vertical swath wall, regardless of the condition of the grain. Wrapping ofthe grain wheel is also done away with and the power needed to run theattachment is compensated for by the efficiency which is attained.-

The structure of my improved device is exceedingly simple, comparativelyinexpensive to manufacture, strong and durable, very reliable, notlikely to easily become out of order, and otherwise well adapted to thepurpose for which it is designed.

With the above object in view, the invention resides in certain novelfeatures of construction, and in the combination and ar-k rangement ofparts as will be hereinafter more fully described and claimed.

Referring to the 4drawing in detail it willV .l

be seen that 5 denotes aframe of conventional construction which i'smounted for` wardly `of ,the ,binder (not shown) riny they usualwell-known manner for supporting the sickle barconstruction 6which isdisposed yhorizontally and is driven `in the usual wellknown manner. Theframe also supports the conveyor 7of well-known construction.V In the ypresent instancey the sickle-bar struc-1k ture 6 and the'` vconveyor 7are operatedr through the shaft 9 which in turn is op-v eratedby chains10. TheV supporting wheel 11 is mounted in the usual `well-known man?ner to one side of the frame -5. #It is ,now the common practice tomount a divider board to one side of thisframe 5. However, in myconstruction this divider board is done away with and there isutilized'afvertical sickle bar construction denoted gener` allyby'theletter Swhich is disposed forwardly ofthe sickle bar lstructure 6 and toone side thereof in alinement with the space usually occupied by thedivider board, that is, approximately in front of the supporting wheel11. The numeral 12 denotes the divider .sill which is attached to theframe at 14 at its rear end and extends laterally and then forwardly andmerges into a `forward extension which is bent at a point forwardly ofthe sickle structure 6 inwardly and has a bracket 15 at its forward endto which a flattened end 16 of a tube 17'is attached as at 18. The rearvend of this tube is bent iml and engages over oneof the guard fingers 19of the vertical sickle structure S. Manifestly the tube 17 is of rigidcharacter, and from this it follows that the tubeV 17 contributes to thedividing capacity of the sill 12 without materially increasing theWeight of said sill, and at the same time thetube 17 by receiving thelowermost finger 19 of the upright cutting mechanism assists in themaintenance of said upright cutting mechanism in working position. Thisvertical sickle structure S includes a vertical stationary bar 20 havingthe usualngers 19 projecting forwardly therefrom. The bar 'y 20 isarranged at the forward end of an mu v upright supplemental frame madeup of an inclined bar 20X connected at one end to the sill l2 and at itsupper end to the upper end of the bar- 2O and appropriately' braced bars2lX and 22 interposed between and connected to the sill l2 and the bar20X. A movable cutter bar 21 is mounted in the stationary bar 2O and hasknives or cutters 22 which ijnovefi-n the-fingers 19 as is clearlyillustrated in Fig. 4. A head 23 is attached to the movable bar 2l andis engaged with a pitman 24 and isalso engaged with the crank of a crankshaft 25 which extends rearwardly being journaled in bearings 26 and 27and at its rear end is operatively connected with a chain 28. The chain28 is operatively connected with the shaft 9.

It is' thought that the construction, operation, and utility of thisinvention will now be clearly' understood without a more detaileddescription of the parts thereof. It willbei noted' that as the binderor other grain-cutting mechanism moves forwardly a clean-cut verticalswath wall is formed regardless of the condition of the grain. Thiseliminates all' the undesirable.features incident to2 the usual* dividerboard struc ture. v l

The present embodiment of the invention has been. disclosed in detailmerely by way of example since in actual practice it attains thefeatures of advantage enumerated as desirable in the statement of theinvention and the above description. It is apparent that changes in thedetails of construction, and

in the combination and arrangement of parts may be resorted. to' withoutdeparting from the spirit or scope of the invention as hereinafterclaimed or sacrificing any of its advantages.

Having thus described my inventionwhatv divider sill having its rear endfixed to the 'i frame and terminating in frontof and to one side of thefirst namedl cutting mecha` nism, a bracket fined on the forward end ofsaid sill and having a rearwardly directed arm spaced above the sill, arigidk tube connected at one end to said arm of said bracket and:extending upwardly and rearwardly from said arm and receiving in itsrear end the loweisnost finger of the second named cutting mechanism,and an upright supple-` mental fraine connected with 'the upright bar ofthe second named' cutting mechanism and the frame `and arranged in rearlof said `upright bar andhaving a rearwardly and downwardly inclinedtopbar and also having intermediate upright bars and braces for thelatter.

In testimony whereof I aihx my signature.
